Nonnegative Matrix Factorization for identification of unknown number of sources emitting delayed signals
Nonnegative Matrix Factorization for identification of unknown number of sources emitting delayed signals
Factor analysis is broadly used as a powerful unsupervised machine learning tool for reconstruction of hidden features in recorded mixtures of signals. In the case of a linear approximation, the mixtures can be decomposed by a variety of model-free Blind Source Separation (BSS) algorithms. Most of the available BSS algorithms …
